Aldebaran is the Bull's fiery eye | Brightest Stars | EarthSky History and mythology of Aldebaran. Science of star Aldebaran. This star glows with the orangish color of a K5 giant star. In visible light, it is about 153 times brighter than the sun, although its surface temperature is lower (roughly 4000 kelvins compared to 5800 kelvins for the sun). Aldebaran is about 65 light-years away, much closer than the stars of the Hyades with which it misleadingly seems associated. The Hyades are about 150 light-years away. Aldebaran is an erratic variable with minor variations too small to be noticed by the eye. It also has a small, faint companion star, an M-type red dwarf, some 3.5 light-days away. In other words, light from Aldebaran would need to travel for 3.5 days to reach the companion, in contrast to light from our sun, which requires 8 minutes to travel to Earth. The three medium-bright stars of Orion’s Belt point to reddish Aldebaran.

Image via SolarEmpireUK How to see Aldebaran. Aldebaran is easy to find. Frequently imagined as the fiery eye of Taurus the Bull, Aldebaran is part of a V-shaped star grouping that forms the face of the Bull. This pattern is called the Hyades. You can also locate Aldebaran using the famous constellation Orion as a guide. Simply locate the three stars of Orion’s Belt. Then draw an imaginary line through the belt to the right. The first bright star you come to will be Aldebaran with its distinctive reddish-orange glow. Aldebaran is the 14th brightest star, but five of those that outshine it are only barely visible or not visible at all from much of the Northern Hemisphere. Aldebaran is primarily a winter and spring star. At least, that is when this red star is most easily visible in the evening sky. By early December, it rises shortly after sunset and is visible all night. Three months later it is high to the south at sunset, and sets at around midnight. By early May, it hangs low about the western sunset glow – and before the end of the month, it’s lost altogether.

It returns to the predawn sky around late June. By the way, although it appears among them, Aldebaran is not actually a member of the V-shaped Hyades cluster. It is actually much closer to us in space than the actual Hyades stars. Constellation Taurus. See Aldebaran marked as the Bull’s Eye? View larger. History and mythology of Aldebaran. Aldebaran is often depicted as the fiery eye of Taurus the Bull. Because it is bright and prominent, Aldebaran was honored as one of the Four Royal Stars in ancient Persia, the other three Royal Stars being Regulus, Antares and Fomalhaut. The name Aldebaran is from the Arabic for “The Follower,” presumably as a hunter following prey, which here likely was the star cluster we call the Pleiades. The latter was often viewed as a flock of birds, perhaps doves. According to Richard Hinckley Allen in his classic book Star Names, the name Aldebaran once was applied to the entire Hyades star cluster, a large loose collection of faint stars.

In Hindu myth, Aldebaran was sometimes identified with a beautiful young woman named Rohini, disguised as an antelope and pursued by her lecherous father, disguised as a deer, Mriga. Apparently several ancient peoples associated the star with rain. The Wikipedia entry notes a Dakota Sioux story in which Aldebaran was a star which had fallen to the Earth and whose killing of a serpent led to the formation of the Mississippi River. Allen notes a number of other alternate names, but precious little mythology is known for Aldebaran separately. Aldebaran is the name of one of the chariot horses in the movie Ben Hur. On a different note, astronomer Jack Eddy has suggested a connection with the Big Horn Medicine Wheel, an ancient circle of stones atop a mountain in Wyoming. Eddy wrote that the ancient Americans may have used this site as a sort of observatory to view the rising of Aldebaran just before the sun in June to predict the June solstice. Interestingly, in about two million years, the American spaceprobe Pioneer 10, now heading out into deep space, will pass Aldebaran.

Aldebaran’s position is RA: 4h 35m 55s, dec: 16°30’35” Bottom line: The star is so Aldebaran huge that, were it in our sun’s place, its surface would extend almost to the orbit of Mercury. Aldebaran: The Star in the Bull's Eye Aldebaran: The Star in the Bull's Eye By Elizabeth Howell, Space.com Contributor | July 18, 2013 09:28pm ET MORE On the morning of Sunday July 15, 2012, the planets Venus and Jupiter joined with the red giant star Aldebaran and the waning crescent moon in a quadruple conjunction. The Pleiades star cluster is nearby. Credit: Starry Night Software Aldebaran is the brightest star in the constellation Taurus and is known as the "Eye of Taurus." The name "Aldebaran" is Arabic, which means "The Follower" because it appears to follow the Hyades star cluster that forms the head of the bull.

The K giant star is slightly larger than our sun, at 1.7 solar masses, and strong winds emanating from it are bleeding away its mass. Aldebaran is older and redder than the sun and preparing to fuse its lightweight core into heavier elements, which is common among stars of its type. Aldebaran has a surface temperature of about 6,760 F (3,738 C) and glows red, similar to Mars — which occasionally passes by the star in the night sky. Because the star's luminosity is well understood, it is sometimes used for comparative astronomy. In 2006, for example, the Cassini spacecraft gazed at Aldebaran through the rings of Saturn to learn more about ring particle concentrations. Locating Aldebaran The star was noted and named in Chinese, Roman and Hindu astronomy, among other cultures. Aldebaran would have been hard to miss for the ancients, given that Taurus is very visible in the winter. The bull, in fact, is one of the oldest documented constellations . Its origins stretch back at least as far as the Bronze Age.

At 65 light-years away, the star is practically a neighbor to Earth. Its apparent magnitude is about 0.85, making it the 14th brightest star in the night sky. Aldebaran's location is: Right ascension: 04 hours 35 minutes 55.2 seconds Declination: +16 degrees 30 minutes 33 seconds HIGHLIGHTS ~ ALDEBARAN Aldebaran, "The Eye of Illumination" Aldebaran, the brightest star in the constellation Taurus the Bull, rises in the fall at sunset, and is the thirteenth brightest star in the sky. Its name comes from the Arabic Al Dabaran, the Follower, because Aldebaran appears to follow the Pleiades through the night sky. As the Eye of the Bull, Aldebaran is called the Eye of Revelation. It is referred to by astronomers and cosmologists as the Eastern Royal Star , one of the four Royal Stars considered the sentinels watching over other stars. It is also known as the Buddhas star, the Star of Illumination, and Gods Eye.

This magnificent star has been used for centuries in navigation, and is known by many civilizations to be connected with the spirits of rain and the fertility of the earth. Approximately 5,000 years ago, the rising of Aldebaran marked the vernal equinox ( 1 ) and marked the beginning of the Babylonian new year. Taurus is often associated with royalty and divine power. Throughout the ages Aldebaran has been spiritually recognized for its alignment with divinity. "... there is a symbolic relation between Aldebaran, the "eye" in the head of the Bull; the third eye, or the light in the head, and the diamond. The consciousness of the Buddha has been called the 'diamond-eye.'" ( 2 ) The Hindus referred to Aldebaran and Taurus as Rohini (the Red Deer), the name of the river in Nepal where the Buddha was born at the time of the May full moon , around 563 BCE. Another Hindu name for Aldebaran is Sataves, which translates to the "leader of the western stars." Pale reddish-orange in color, Aldebaran has a companion red dwarf star that shares its motion throughout space.

Located slightly south of the ecliptic, in the path of our earths moon, Aldebaran has a magnitude of 1.2 and is one of the few 1st magnitude stars the moon may occult . Approximately 40 times the size of our sun, Aldebaran is 68 light years from the Earth, and is about 3 times the brilliance of Polaris, our current North Star. In addition to the star Aldebaran, there are two other very beautiful and famous star clusters in the constellation of Taurus: the V-shaped Hyades at the head of the bull, and the Pleiades in the shoulder. To locate Aldebaran or Taurus, follow the line of the three stars that make up the belt of Orion; they point directly west toward Aldebaran. Look up during the fall and winter months just after sunset, and youll see Orions Belt and Aldebaran rising in the east, traveling in a northwesterly direction. Aldebaran, the star of illumination, is directly across the zodiac from Antares , the star of anger, pride and revenge.

In the only exact opposition of two major stars; Aldebaran is located at 9 degrees of the sign Gemini, with Antares at 9 degrees of the sign Sagittarius. Aldebaran is said to be a portal to the mysteries of the mind and when balanced with the fixed star Antares, a portal to the mysteries of the heart, this creates a powerful stargate axis that is illuminated bi-annally when the Sun passes by Aldebaran at the first of June and then Antares about six months later. Recently Pluto passed through the constellation of Scorpio and conjoined Antares, also known for its transformative qualities. Pluto visits Scorpio only once every 248 years. During its sweep through this part of the zodiac, Plutos orbit brings it closer to the Sun than Neptune for approximately 20 years. Pluto is a dynamic force of creation and destruction. Pluto, the first ray planet of will power and purpose in our solar system assists in the destruction of the lower desires so that more highly evolved qualities can be expressed by the human being. In the destruction of old forms ~ be they physical, astral or mental ~ Pluto literally changes their atomic structure.

Pluto causes major changes and forces the transcendence of personal desires into a more universal orientation. Pluto is the planet of death and rebirth. It personifies the destruction of things whose time has come to an end, and the regeneration of what is new. It is like decaying autumn leaves becoming nutrients for the spring; the caterpillar changing into a butterfly. It is the transformer that stimulates and catalyzes the Will . For more about Pluto and the quality of Transformation, click here . This rare cosmic event of Pluto's having passed by Antares is significant, as it was also directly opposed to Aldebaran, the Buddhas star of Revelation and Illumination. This brought an opportunity for humanity as a whole to evolve the energies of conflict, anger, pride and revenge, as we had the opportunity to call upon the qualities of Revelation and Illumination to work with the energies of Pluto on Antares toward bringing about transformation and evolution : In stellar myth, Aldebaran is Vision Holder for the starseed mission on Earth, defining what emissaries of light can best accomplish to serve humanity through evolutionary transition.

In down to Earth terms, Aldebaran holds the vision for global leaders and world servers, inspiring the administrative planning of world affairs, specifically for physical logistics and a global infrastructure designed to support humanity through evolutionary unfoldment and global change. Prominent alignments with the Aldebaran / Antares axis can express into the political and global arena. The visions that many people attune to regarding alternative living centres, educational centres, emergency preparedness programmes, etc., are parts of the inspiration from this star’s emanations. Aldebaran can indicate involvement with physical places and projects supportive of alternative modalities of living. It inspires business that supports family. Aldebaran inspires us to take the physical action required to manifest our visions. - Nick Anthony Fiorenza, The Lunar Planner In the sign of Taurus, when desire is transmuted into aspiration , darkness gives place to light and illumination . The eye of the bull, the spiritual third eye or the "single eye" of the New Testament, is opened. "If thine eye be single, thy whole body shall be full of light," said the Christ (Matthew 6:22). This single eye takes the place of the two eyes of the personal self.

( 3 ) As the attention of humanity becomes focused upon spiritual attainment, we tread the Way of Revelation . Life is filled with revelation. The entire evolutionary process is essentially nothing but a growing revelation. The two concepts Evolution and Revelation go together. As we evolve, we perceive more than we ever knew was existent or perceptible, yet we are only perceiving what has always been there. The Way of Revelation is through the discovering and discarding of our own limitations. ( 4 ) Revelation, as defined by The Dictionary of Scripture and Myth, is a "symbolic communication from the higher nature to the lower, imparting truths of the invisible universe and the soul. As revelation does not and can not arise from the lower nature, it is self-evident that the lower or objective mind of man does not compose the revelation, but is merely the receptive vessel into which the Divine message is poured." Revelation is related to God Immanent, to God in form, to God in the human heart, and to that veiled and hidden Supreme Reality motivating all existence ~ forever consciously aware of Itself. Revelation is a progress of penetration. First into the Mind, then into the Heart , and finally into the Purpose of Deity.

( 5 ) As the star of illumination, Aldebaran irradiates the Way using the applied power of transformation. In seeking illumination, we can cultivate the ability to use the mind as a reflector of soul light. ( 6 ) An increased understanding about the process of revelation may help us comprehend the quality and significance of Aldebaran. "Angel of Healing" © Aeoliah One way we receive revelation is through contact with the soul . The more consciously we desire, demand and will such contact, the closer we are to receiving the next needed revelation. How clearly we perceive the revelation depends on our ability to still the mind and listen to the voice within. One of the most difficult aspects of our service is to understand correctly the precipitating truth, information or revelation that is being impressed. We need time to absorb the revelation and incorporate it into a useful present time form. How does one become a living example of this divine understanding and better understand the significance of the star Aldebaran? One suggestion is to meditate on the triangle created by the Pleiades , the Great Bear , and our solar system . Based on image "Music of the Spheres" by Bernard Xolotl Imagine the pathway the energy follows to reach our Earth.

See the energy of the Will as a brilliant golden light emanating from the constellation the Great Bear. Visualize this light flowing to one of the seven stars of the Pleiades, observe the star it is naturally magnetized toward. Know the energy is being slowly stepped down in vibration as it reaches this star. Watch it leave the Pleiades and enter into our solar system. Visualize Aldebaran, the star of illumination, focusing like a lens the light force, Fohat , the Active Intelligence, to the Earths North Pole. Then see this force being absorbed by the Soul of Humanity. Visualize a golden thread of light entering the top of your head, and open to receive revelations and insights about your purpose in the divine Plan . When the energy of the light force is released to nations, races and individuals it produces two effects: the increase of the self-will, demonstrating as cleavages, separate desires, goals, or ideas of a nation, state, family or the individual, without regard for the need of the whole. The second effect stimulates the Will-to-Serve the Plan, the whole, and produces unity and harmony, beneficial to the entire process of evolution.

Besides Aldebaran, the other three Royal Stars in the heavens are Antares in the constellation Scorpius the Scorpion, the Western Royal Star, Regulus in the constellation Leo the Lion, the Northern Royal Star, and Fomalhaut in the constellation Pisces Austrinus, the Southern Fish (very close to the constellation Aquarius), the Southern Royal Star.

Aldebaran is by far the brightest, and therefore the Alpha , star of the constellation Taurus .

The ancient name, from Arabic, means "the Follower," as the star seems to follow the Pleiades , or Seven Sisters star cluster , across the sky. Aldebaran, 67 light years away, is positioned in front of the sprawling Hyades star cluster (in mythology, half-sisters to the Pleiades) that make the head of Taurus the Bull, but is not a part of it, the cluster (at 150 light years) over twice as far away. Nevertheless, it makes a fine guide to it. In most renderings of the constellation , Aldebaran makes the celestial Bull's eye. As part of a constellation of the Zodiac , Aldebaran is close to the Sun's path, the Sun passing to the north of it about June 1, the star also regularly covered, or occulted, by the Moon . This class K (K5) giant star , of first magnitude (0.85) and 14th brightest in the sky, is a low-level irregular variable star that fluctuates erratically and to the eye unnoticeably by about two-tenths of a magnitude.

Aldebaran's surface temperature of 4010 degrees Kelvin (compared to the Sun 's 5780 degree temperature) gives it a distinct orangy color not all that dissimilar to that of Mars, which commonly passes it. Allowance for infrared radiation reveals the star to have a fairly high luminosity 425 times that of the Sun, which leads to a radius of 43 times solar. A projected equatorial rotation velocity of 5.2 kilometers per second gives the star a rotation period that could be as long as 400 days. The duration of disappearance in lunar occultations, as well as direct measure of angular diameter through interferometry, give an angular diameter of 0.01996 second of arc (the apparent size of a US nickel seen at a distance of about 50 kilometers), the star a leader in the number of such measures. That combined with distance gives a physical diameter of 44 times solar, in excellent agreement with the one found from luminosity and temperature. From the theory of stellar structure and evolution, Aldebaran carries a mass of around 1.7 times that of the Sun.

Most class K giants are quietly fusing their internal helium cores into carbon and oxygen. Aldebaran, on the other hand, seems to be in a preliminary state in which a still-dead helium core is contracting and heating, causing the star as a whole to continue to expand and brighten. Consistent with its large size and luminosity, it's also known for a strong wind, through which it's beginning to lose mass, which surrounds it out to about 100 Astronomical Units. Within only another few million years, the star will top out at around 800 solar luminosities as it fires its helium, then shrinks and dims some to become one of the usual K-giant crowd. If Aldebaran were in our Solar System, it would extend halfway to the planet Mercury and would appear 20 degrees across in our sky, its great luminosity making life on Earth quite impossible. For a time, Aldebaran was thought to harbor its own planet (discovered through shifts in the star's velocity), but it has never been confirmed.

Such would be counter to the usual finding that stars with planets tend toward high metal abundances, as Aldebaran's iron content (relative to hydrogen) is about half that of the Sun's.

Aldebaran - Alpha Tauri | Constellation Guide Constellation Guide Constellations: A Guide to the Night Sky Aldebaran by admin Aldebaran, Alpha Tauri, also known as the Eye of Taurus, is an orange giant star located at a distance of 65 light years from Earth. It is the brightest star in Taurus constellation and the 14th brightest star in the night sky. Aldebaran has a luminosity 518 times that of the Sun (153 times in visible light).

The name Aldebaran (pronounced /ælˈdɛbərən/) comes from the Arabic word al-dabarān, meaning “the follower.” The name refers to the Pleiades cluster ( Messier 45 ), which the star appears to be following across the sky. Orange or reddish in colour, Aldebaran has the stellar classification K5 III and an apparent magnitude that varies from 0.75 to 0.95. It is classified as a slow irregular type LB variable star and has the designation CSV 6116 in the Catalogue of Suspected Variable stars. The star’s variability is not visible to the naked eye. Aldebaran has evolved off the main sequence stage of its life cycle and exhausted the supply of hydrogen fuel in its core. It is now fusing hydrogen in a shell around the helium core. As a result, the star has brightened and expanded to a radius 44.2 times that of the Sun. Aldebaran and Sun in scale.

If Aldebaran were to replace the Sun in the centre of the solar system, the star’s surface would extend halfway to the orbit of Mercury and would extend across 20 degrees in our sky. The helium burning stage typically lasts tends to hundreds of millions of years, or about 700 million years for a star with a mass equal to the Sun’s, and Aldebaran has 1.7 solar masses. Aldebaran will reach about 800 solar luminosities within the next few million years. Eventually, it will lose much of its current mass through its strong stellar wind and expel its outer envelope to form a planetary nebula, leaving behind a white dwarf. The star is cooler than the Sun, with a surface temperature just under 4,000 K, compared to the Sun’s 5,800 K. It is a very slow rotator, completing a rotation every 643 days. Aldebaran location Aldebaran is very easy to find in the sky. To locate the star, observers can just follow the line formed by the three stars of Orion’s Belt to the right (in northern latitudes) or to the left (in the southern hemisphere).

Aldebaran is the first bright star that appears along that line. The best time of year to observe Aldebaran is in the fall and winter months, when the star and Orion’s Belt rise in the east in the evening and move to the northwest over the course of the night. Star system There are five faint stars appearing near Aldebaran, but most of them are just optical companions. The stars were given designations Aldebaran B through Aldebaran F in the order of discovery, while the primary star is designated Aldebaran A. Aldebaran and the Hyades cluster. Image: Thomas Bresson Aldebaran B is a red dwarf with the stellar classification M2V. It has an apparent magnitude of 13.6 and an absolute magnitude of 11.98. It is separated by about 607 astronomical units from Aldebaran A. Several surveys have indicated that the two stars may share a common proper motion and may not be just optical companions, but form a physical binary star system. However, as the star B is too faint and appears too close to Aldebaran A, astronomers have not been able to confirm this with any degree of certainty.

The stars Alpha Tauri C and D are gravitationally bound to each other and form a physical binary system. They are K5 and M2 dwarf/subdwarf stars separated by about 34 astronomical units. The stars lie far beyond Aldebaran A and belong to the Hyades cluster. FACTS Aldebaran marks the right eye of the celestial Bull , while Ain, Epsilon Tauri, marks the left eye. Aldebaran lies in the same line of sight as the Hyades open cluster and appears as the brightest member of the famous cluster. The Hyades cluster , known for its bull’s head V-shape, is in fact some 150 light years distant from Earth, more than twice as far away from us as Aldebaran. In this July, 1997 still frame captured from video, the bright star Aldebaran has just reappeared on the dark limb of the waning crescent moon in this predawn occultation. Photo by Bart Benjamin. Alpha Tauri lies close to the ecliptic, the apparent path of the Sun, Moon, and planets across the sky, and is often occulted by the Moon.

The occultation makes it easy to get a good estimate of the star’s size by taking into account the time it is covered and watching it from different locations. The star is in conjunction with the Sun around June 1 every year. Astronomers reported detecting a substellar companion orbiting the star in the 1990s, but subsequent studies have not confirmed this. If it exists, the companion has a mass at least 11.4 times that of Jupiter and orbits the star every 643 days at a separation of 2 astronomical units. The orbital period of the suspected companion matches the star’s rotation rate. Two other stars that exhibited similar long-period radial velocity oscillations in the same study were Arcturus in Boötes constellation and Pollux in Gemini . The authors of the study concluded that the oscillations were likely intrinsic to the stars and not caused by the gravitational effect of a substellar companion. Aldebaran is one of the brightest stars in near-infrared wavelengths. It has a near-infrared J band magnitude of -2.1 and is only fainter than Betelgeuse , R Doradus, and Arcturus . Aldebaran and Hyades.

Image: Thomas Bresson The star was known by many different names over the millennia. Persian observers knew it as Tascheter. It was the Eastern Royal Star, one of the Four Royal Stars in ancient Persia, along with Regulus in Leo constellation , Antares in Scorpius , and Fomalhaut in Piscis Austrinus . Aldebaran is also known as the Buddha’s Star, God’s Eye, or the Star of Illumination. About 5,000 years ago, the star’s rising marked the vernal equinox and the beginning of the Babylonian new year. Ancient Romans called the star Palilicium. The name is derived from Palilia or Parilia, referring to the feast of Pales, the feminine form of Pan. The Chinese name for the star is Bìxiùwŭ, or the Fifth Star of the Net. In the Middle Ages, Aldebaran was sometimes called Cor Tauri, which is Latin for the Heart of the Bull. In Hindu mythology, the star is known as Rohini, one of the 27 daughters of Daksha given to the god Chandra as wives.

Chandra, the Moon god, fell in love with Rohini and spent all his time with her, neglecting his other wives. This angered Daksha, who cursed the god to suffer from tuberculosis. Other gods intervened and the curse was changed so that Chandra suffers tuberculosis for 15 days and gets well for the other 15 days, which explains the lunar phases. Map of the Hyades cluster from a southern perspective. Image: Roberto Mura The Seris people in Mexico saw Aldebaran as a star providing light for seven women giving birth. The seven women were represented by the Pleiades cluster. The Dakota Sioux had a legend in which Aldebaran fell to Earth and killed a serpent, which led to the formation of the Mississippi River. In Aboriginal culture, in the Clearance River of New South Wales, Aldebaran was known as the Ancestor Karambal, who stole another man’s wife and was then tracked down by her husband, who burned the tree in which Karambal was hiding. It is believed that Karambal then rose to the sky as smoke and became the star Aldebaran. Aldebaran is often featured in works of science fiction, including H.P.

Lovecraft’s The Cthulhu Mythos (1921-), E. E. “Doc” Smith’s Lensman series (1934-1948), Leigh Brackett’s novel The Starmen (1952), Alfred Bester’s classic The Stars My Destination (1956), Ursula K.

(1988), and Kim Stanley Robinson’s Blue Mars (1996). The star is also featured in Luiz Eduardo de Oliveira’s comic book series Aldébaran (1994–1998). There are also references to Aldebaran in episodes of Star Trek: The Original Series, The Next Generation, and Enterprise, and also in Buck Rogers in the 25th Century. “Taurus”, plate 17 in Urania’s Mirror, a set of celestial cards accompanied by A familiar treatise on astronomy… by Jehoshaphat Aspin.

Alderaan is a planet in a galaxy far, far away, while Aldebaran is a star in the Milky Way Galaxy. Aldebaran is also mentioned in several classics outside science fiction, including Thomas Hardy’s novels Far from the Madding Crowd (1874) and Tess of the d’Urbervilles (1891), James Joyce’s Ulysses (1922), and George Orwell’s Down and Out in Paris and London (1933). The star Borgil in J.R.R. Tolkien’s The Lord of the Rings (1954-1955) has also been positively identified as Aldebaran. Other references to the star include the games Star Control, Frontier: Elite II, FreeSpace 2, and Escape Velocity Nova.
